I2P is an anonymizing network, offering a simple layer that identity-sensitive applications can use to securely communicate. All data is wrapped with several layers of encryption, and the network is both distributed and dynamic, with no trusted parties.

Many applications are available that interface with I2P, including mail, peer-peer, IRC chat, and others.

Installation

I2P is available in the AUR, with i2pAUR providing compilation from source, and i2p-binAUR providing a precompiled binary.

Usage

First, invoke the i2prouter daemon:

SysV

/etc/rc.d/i2prouter start

(add i2prouter to the DAEMONS array in your /etc/rc.conf to start at boot)

systemd

systemctl start i2prouter.service

(issue systemctl enable i2prouter.service to start at boot)

This will launch the daemon under the system user 'i2p'. Next, open your browser of choice and visit the I2P welcome page at

127.0.0.1:7657/home

From here you can navigate to I2Ps configuration and statistics pages, and links to "Eepsites of Interest" (eepsites being sites available only through the I2P network, similar to how .onion sites are only available through the Tor network). Also, be aware that eepsites are unavailable until the daemon has bootstrapped to the network, which can take several minutes.
